Many thanks for your replies, the suggestions work perfect!
I have another strange problem. When I try to use the following code \documentclass[a4paper]{article} \usepackage{xltxtra} \setmainfont{Cambria} \begin{document} Ἀριθμὸς \char"1F08 \end{document} I get for character "1F08 Greek Capital Letter Alpha with Psili" something that looks like A' with the accent to the right, not the left. With Arial font, I get the correct letter. Is there something wrong with the font itself, or with how XeTeX uses the font? I have not installed any fonts, it's just the Cambria font that Word has. In Word, 'A looks correct when I insert symbol 1F08 Thank you -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
